Specification of Letters Patent.

Application filed March 19,1915. SeriaiNo .15,482. e

by declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains' to make and-use the same. i

This invention relates to tools, and more particularly to a blacksmiths tool for use in connection with lister shares or blades, and the primary object of the invention is to provide a tool for holding the lister blades while being sharpened, and which will prevent the warping or shrinking of the blades when heated prior to the sharpening of the same, insuring the proper fitting of the blades or shares upon the lister after it has been sharpenedf Another object of this invention is to provide a tool as specified which embodies a handle, rotatably supporting a transversely extending lister' blade engaging member which is adjustable longitudinally, for accommodation to lister. blades of various sizes, and also to provide means for holding the transversely extending blade engag ng member in various adjusted position, for

' regulating the angle of the handle with respect to the lister share or'blade.

' With the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will behereinafter ings, v1 designates a lister share or blade,

which has the ordinary type of openings or holes 2 formed therein, for attaching the same to a standard for supporting the blade.

The tool o-embodies a main body portion 6,

which is constructed of any suitable metal,

and is composed of sections 7 and 8, which extend onlines parallel to each other and are connected by a transversely extending,

section 9. The section 8 of the body Ghas a handle or hand grip 10 formed upon-its outer end. The section 7 of the body 6 has its outer end 'enlarged,'and bifurcated for forming bearing arms 11 and;12, which are provided with alining bearing openings 13, through which a sleeve 14 extends. The

sleeve 14 is slidably mounted in the bearing openings 13, and it has-an arm 15 swivelly connected to one end thereof,as is shown at at right angles thereto, for insertion through Patented Oct. 12, 1915 one of'theopenings 2 in the lister share 1,

and. for engagement opening.

The sleeve 14 is internally screw threaded, and it has a lister'blad'e engaging arm' 17 adjustably'connected thereto and extending out of the sleeve oppositely from the arin 15. The arm 17 has its outer end bent sub stantially at right angles to the main body portion thereof, for forming an inserting point 19 for insertion through one of the openings 2 in the lister blade 1. A ratchet wheel 20 is mounted'upon the sleeve 14, and is held for'rotation with thesleeve, by means of a blind set screw 21, which engages a flat surface 22 formed upon the outer surface of the sleeve 14. The ratchet wheel 20 with the wall of the is provided with a plurality of circumferentially spaced recesses 23, which are provided for receiving, at different times, the inserting end ofthe catch 24. The catch 24 is formed upon the inner end of an arm 25, which is slidably seated within a bore 26 formed in the section 7 of the body 6. The bore 26 has its end, facing the arms 11 and 12, enlarged, in which enlarged section is seated a spiral spr'ing27; One end of the spiral spring engages the shoulder which is formed by the enlargement of the. bore 26, and the other end ofthe spring engages an annular collar 28, formed upon the rod 25,

ing the same.

at the inner end of the inserting point or end 24 of the catch. The outer end of the rod 25, which projects out of the section 7, has a link 29 connected thereto, which link is in turn connected to one end of a thumb lever 30. The thumb lever 30 is pivotally connected at 31 to the section 8 of the body 6, and it has a thumb engaging arm 82 formed thereupon and extending toward the hand grip 10 of the body 6. The pivotal movement of the thumb lever 30 will move the rod25, for moving the catch 24 out of any one of the circumferential recesses 28, for permitting the rotation of the ratchet 20, sleeve 14 and the arms 15 and 17 carried by the sleeve.

When using the tool, for facilitating the sharpening of a lister share or blade, the angled ends of the arms 15 and 17 are inserted through the corresponding pair of the openings 2 formed in the lister share, and the sleeve 14 is rotated, by oscillatory movement of the body 6, for feeding the arm- 17 outwardly until a firm and secure grip is formed between the angled ends of the arms 15 and 17, and the lister share 1, for holding the share and handle firmly attached, which provides a handle for conveniently moving the share while sharpen- Theoutward feeding of the arm 17, is accomplished by the rotation of the sleeve 14 and the ratchet 20 in one direction, and the ratchet movement is employed,

. or in other words When body 6 reaches the limit of its movement in the direction necessary for feeding the arm 14 outwardly, the lever 30 is operated, which releases'the catch 24 from engagement with the ratchet 20, and the lever is moved in a reverse direction, the desired distance, after which the lever 30 is released and the catch 24 moved into one of the openings 23, by the action of the spring 27. The angled ends of the arms 15 and 17 being inserted in the openings 2 of thelister share, will also prevent warping, shrinking or other changes in the form of the share during the heating, and maintain the spacing of the openings so that they will not lose register with those formed in the share-supporting standard.

In reducing the invention to practice, certain minor features of construction, combination and arrangement of parts may necessitate alteration to which the patentee is entitled, provided such alterations are comprehended within the scope of what is claimed.

What is claimed is 1. In a tool as described, a body portion, a sleeve rotatably carried by one end of said body portion, an arm swivelly connected to one end of said sleeve, a second arm adjustably connected to the opposite end of said sleeve, and means for moving said adsleeve, said arms having their ends bent for operative engagement with a share.

2. In a lister share holdlng tool, a body,

a share engaging member rotatably carried by one end of said body and extending transversely thereto, and means for adjusting the length of said lister share engaging member.

3. In a tool for holding lister shares, a body having a hand grip formed on one end thereof, a transversely extending sleeve rotatably carried by the other end ofsaid body, an arm swivelly connected to and extending longitudinally from one end of said sleeve, an arm adjustably carried by and extending longitudinally from said sleeve oppositely to said swiveled arm, said arms having their outer ends angled for operative engagement with a share, and means carried by said body for arresting rotation of'said sleeve. v

4. In a tool for holding lister shares, a body, a hand grip formed upon one end of said body, the other end of said body being bifurcated for forming spacedla rms, bearing openings formed within said spaced arms, a sleeve rotatably mounted within said bearing openings, an arm swivelly connected to and extending longitudinally from one end of said sleeve, a second arm adjustably connected to said sleeve and extending longitudinally from the endof said sleeve opposite. to said swivelly connected arm, a ratchet mounted upon said sleeve intermediate of said spaced arms, a'catch carried by said body, and means for moving said catch into or out of engagement with said ratchet.
